SPORTING-GUN CARTRIDGE PLUG.

Application filed December 10. 1924, Serial No. 755,080, and in BelgiumDecember 14, 1923.

called Iris type. which comprises a corkspoolor bobbiirshaped memberhaving its intermediate portion fitted with a band of paraflined felt.

According to my invention, I construct the two end'portions or disks andthe interi mediate portion or core of separate pieces of cork or similarmaterial, and I fit the core with a band of felt or other suitablesubstance which is impregnated with an agglutinant such as paratlin thatwill soften and fuse under the heat of the gas of explosion when thecartridge is fired. Preferably, the three parts specified are fastenedtogether by means of the paraffin for convenience in loading thecartridge; but such attachment. however, will be terminated by themelting of the paraffin, as above explained, and the parts will separateon leaving the barrel. This detachment will enable the parts to respondmore effectively to the impulse to which they are subjected, while atthe same time preventing any danger of the wadding sticking in thebarrel: and it also serves to reduce the weight of the wadding which isopposed to the spread of the shot, so that the ballistics are improved.The core itself, for the same reason, constitutes an effective gascheck, since it expands in consequence of the pressure imposed upon itand, in turn. causes its felt strip to bear against the wall of thebarrel, thus preserving to the full extent the velocity, penetratingforce and carry of the charge.

The construction of the improved wadding can be carried out in variousways, ac-

cording to one of which. the first cork disk is placed in a metal moldof the proper caliber which rests on a plate also made of metal. Theintermediate disk or core, which is itself of appreciably smallerdiameter than the first disk, but which is rendered of equal diametertherewith by the addition of its peripheral band or strip of felt, isthen placed on the first disk and a suitable agglutinant, preferablyparaffin, is poured into the mold, whereafter the third or top disk 1spositioned on top of the intermediate disk before the agglutinant hascompletely cooled and hardened, thus binding the three disks together.Removal of the wadding from the mold may beeffected by the chuck-ormandrel of an automatic or pedal-operated gauge.

In place of the method just described, the resilient cores, previouslyfitted with their felt strips. may be introduced into suitable molds andthen paraflined in the manner above explained. after which they arecarefully removed and boxed say by the hundred or two hundred; doublethe number of end disks then being packed in a separate compartment inthe same box. At the moment of loading, it is sufiicient merely tointerpose a core between two of the larger end disks; this operationoccasioning no confusion and being much simpler and easier in fact thanthe ordinary operations of assembling and loading multiple-part waddingswhich frequently embody from six to eight different component members,some of which are difficult to distinguish.

In order to enable a more complete understanding of the invention to beobtained, the accompanying drawing shows one embodiment thereof, and inwhich:

Figure 1 represents the three component parts of the improved waddingseparated from one another;

Fig. 2 represents the parts assembled, but without the felt strip on theintermediate part or core;

Fig. 3 is a vertical section through the finished wadding; and

Fig. 4: is a side elevation thereof.

In said figures, B and G indicate the two end disks of the wedding, andE the intermediate disk or core which is of appreci ably smallerdiameter than the first two disks, all three disks being made of cork orother suitable resilient fibrous material. These parts may be of anydesired shape and size (one of them may be frusto-conical) according tothe results to be obtained, and the end disks may be recessed orapertured in order to facilitate the introduction and seating of thecore, while the latter may be perforated for the purpose of increasingboth the propulsion and the checking effect by the action of compressedair.

The cor E is encircled by the band or strip D of felt or the like whichis subsequently impregnated with paraffin or other suitable agglutinant,as explained above.
